FIG. 7 is a View with the outer pair of top panels locked over the innerpair of panels and the box in a closed or packaged form.

Referring now to the drawings in which the various parts are indicatedby numerals, box 11, as shown in FIGS. 5, 6 and 7, is formed from asomewhat rectangular flat blank 13 of paperboardor similar sheetmaterial. Blank 13 includes basically four sections 15, 17, 19 and 21,as best seen in FIG. 1. Longitudinally and transversely extending foldlines demarcate various portions of blank 13. A first substantiallycontinuous fold line 25 and a second fold line 27 extend respectivelysubstantially the length of blank 13. Transversely extending fold lines29, 31 and 33 extend respectively between fold lines 25, 27 and definesections 15, 17, 19 and 21 of the blank. Each of the four sectionsincludes side, bottom, and top portions which form, respectively, theside, bottom and top panel elements of the box. Side portions 35, 37, 39and 41 of the respective blank sections are demarcated by fold lines 25,27 and by transversely extending fold lines 29, 31 and 33. Bottomportions 43, 45, 47 and 49 extend outwardly from first fold line 25 andICC respectively from side portions 35, 37, 39 and 41. Top portions 51,53, 55 and 57 extend outwardly from second fold line 27 and respectivelyfrom side portions 35, 37, 39 and 41. Box 11 is shown as beingcube-shaped with a square base and a height equal to the base length ofa side; however, the design of the box is such that the height may bevaried to correspond to the height of the item to be packaged.

Included respectively in bottom portions 43, 45, 47 and 49 are bottompartition portions 59, 61, 63 and 65, and bottom portions 43, 47 includerespectively bottom partition extension portions 67, 69. Fold lines 71,73, and 77 and fold lines 79 and 81 demarcate the various portions ofbottom portions 43, 45, 47 and 49. It will be noted that the distancesrespectively between fold lines 71, 73, 75 and 77 and first fold line 25are equal and that this distance is one-half the distance of the baselength of a side of the box, that is, one-half the width of a side ofthe box.

The top partition portions respectively of sections 15, 17, 19 and 21respectively include top partition portions 83, 85, 87 and 89. Foldlines 91, 93 and 95 integrally secure respectively top partitionportions 83, 85 and 87 to the main body of top portions 51, 53, 55. Toppartition portion 89 is secured to handle portion 96 which, in turn, issecured to top portion 57. Fold lines 91, 93 and 95 are disposedrespectively a distance from fold line 27' which is substantially equalto one-half the base length of a side of the box.

Handle portion 96 includes alike and U-shaped half portions including aninner half portion 97 and an outer half portion 99. Half portions 97, 99are secured along a medianly disposed fold line 101 with the respectiveleg portions extending oppositely. Inner half portion 97 is integrallysecured along respective fold lines 103 and 103 at the respective baseof each leg to top portion 57. Top partition portion 89 is joined at therespective base of each leg of outer half portion 99 of handle portion96. Oppositely extending ear portions 107, 107 are included in toppartition portion 89.

Recesses 109, 109 are disposed respectively in top partition portions85, 89. Recesses 109, 109' are medianly disposed and extend transverselyinward from the marginal edges respectively of top partition portions85, 89. Slots 111, 111 extend transversely and substantially bisectrespectively top partition portions 51, 55. Slots 111, 111' respectivelyintersect fold lines 91, 95 and extend substantially half the width ofrespective top partition por tions 83, 87. Slots 111, 111' preferablyterminate respectively at the inward ends thereof a short distance fromsecond fold line 27. Obliquely extending slits 113, 113' extendrespectively between the inward ends of slots 111, 111' and second foldline 27. Two outwardly extending tab portions 115, 115 are integrallysecured to top portion 53 of section 17 of the blank. A flap 117 issecured to side portion 35 along a fold line 119 extending substantiallybetween first fold line 25 and second fold line 27.

Four adhesive bindings preferably secure the erected box; two bindings121 respectively are in the lower area St the box for securing thebottom partition portions of the blank; a binding 123 is provided forlaminatingly securing the handle; and a binding 125 is provided forjoining the opposite ends of blank 13 and for joining flap 117 ofsection 15 to the edge of side portion 41 of section 21.

In erecting the box, the necessary folds are made along the respectivefold lines. The various panels joined by a respective fold line are allsubsequently in right-angular relationship in the erected box except forhandle half portions 97, 99 which are in parallel abutting relationship.

The folds are all made along the respective fold lines of the blanktoward the subsequent inside of the box.

Handle 96 is formed by double-folding handle half portions 97, 99 andsecuring these portions with glue or other such adhesive material. Thetwo bindings 121 in the lower portion of the folded box blank are formedrespectively by laminatingly securing bottom partition extension 67 ofsection 15 with bottom partition 61 of section 17, as by glue or thelike, and by laminatingly securing partition extension 69 of section 19with partition portion 65 of section 21, as by glue or the like.

In erecting the box, side portions 35, 37 are rightangularly foldedalong fold line 29, and side portions 39, 41 are right-angularly foldedalong fold line 33. The box in this stage of erection is substantiallyin two parts, joined along fold line 31 and including a first part ofsections 15 and 17 and a second part of sections 19 and 21. To completethe erection of the box, the two parts are interlocked at the bottomportions thereof, and side portions 35, 41 are right-angularly joined bybinding 125. Binding flap 117 is right-angularly formed along fold line119 and is laminatingly secured along the inside surface of said portion41.

In the erected box, four upstanding partitioning panels are formed inthe lower area of the box, as best seen in FIG. 3. The four partitioningpanels include respectively a pair of oppositely disposedsingle-thickness partitioning panels and a pair of oppositely disposeddouble-thickness partitioning panels. The pair of single-thicknesspanels are formed respectively from bottom partition portions 59 and 63.The double-thickness partitioning panels are formed respectively bylaminatingly joining bottom partition extension portion 67 to bottompartition portion 61 and by joining bottom partition extension 69 andbottom partition portion 65.

It may be desirable in certain applications to delete the bottomextension portions 67, 69 from the box blank, or to eliminate bindings125. It may also be desirable to employ contact or pressure typeadhesive means to the respective surfaces to be joined, so that the boxmay be readily erected at the place of use. It may also be desirable incertain applications to fasten the respective parts at bindings 121, 123and 125 with wire staples or the like. It may further be desirable toeliminate binding flap 117 and substitute therefor binding tape forjoining side portions 35 and 41.

In packing or closing the erected box, the four cylindrical items areplaced in the four square partitioned-off areas (FIG. 3). The topportions 51, 55 of sections 15, 19 are folded over the items, forming aninner pair of top closure panels (FIG. 6). The top portions 53, 57 ofsections 17, 21 are then folded over the inner pair of closure panels,forming an outer pair of closure panels (FIG. 7) and completing theclosure of the box.

Referring to FIG. 6, it will be noted that slots 111, 111' respectivelyof the inner pair of top closure panels align to form a continuous slot.It will further be noted that the top partition portions respectively ofthe pair of top portions are abuttingly parallel and depend downwardlybetween the items contained in the box. The top partition portions 85,89 of the outer pair of closure panels are in parallel abuttingrelationship and extending through the continuous slot formed by slots111, 111. Recesses 109, 109 of the top partition portions 85, 89straddle respectively portions 127, 127 of extension portions 83, 87 ofthe inner pair of top portions. The partition portions 83, 87 and 85, 89of the closed box form double-thickness right-angular X-shapedpartitioning means for separating the items contained. In closing thebox, the oppositely disposed ear portions 107, 107 are urgedrespectively through the obliquely extending slits 113, 113. Urging earportions 107, 107' past slots 111, 111 securely closes or locks the box.As the outer pair of closure panels are folded inwardly together, tabportions 115, 115' are inserted underneath the respective oppositelydisposed corner edge portions of top portion 57, and as the box islocked by ear portions 107, 107, the tab portions 115, 115' provideadditional means for securely closing the box.

Although the present invention has been described and illustrated withreference to a preferred embodiment, it is to be understood that it isnot to be so limited since changes and modifications may be made thereinwhich are within the full intended scope of this invention ashereinafter claimed.
